GMR 600/100 Series Installation Instructions

Failure to avoid the following potentially hazardous situations could result in 

an accident or collision resulting in death or serious injury.

The radar radome transmits electromagnetic energy. Ensure that the radome has 

been installed according to the recommendations given in this guide, and that 

all personnel are clear of the radome before switching to transmit mode.
When navigating, carefully compare information displayed on the unit to all 

available navigation sources, including information from visual sightings,
